CCM 4V

Description

The CCM 4V was created in answer to requests for a cardioid with its main axis along the side. In addition to its usefulness in the concert hall, this microphone type is of particular value in speech recording, since its slight emphasis around 10 kHz helps to improve intelligibility.

The directional response is especially well maintained even at higher frequencies, due to the acoustically transparent housing. There is less high-frequency emphasis of off-axis sound than occurs with most small, axial-response cardioids. The CCM 4V still sounds somewhat brigher than the CCM 4, however, because of its overall frequency response.

Practice

The CCM 4V may be easier to use in near-coincident setups than the CCM 4: the microphone bodies do not get in each other's way.

Product History

• 1994: Launch of the CCM, hybrid technology circuit. The capsule part is identical to the MK capsules from the beginning  
• 2016: better RF filter to protect from interferences
• 2017: Polarization voltage generator now with higher frequency above 200 kHz due to downpitching in sound design applications.
